Patent JP-H01266480-A (JP)
Title: Refrigerator
Inventor: HORIE JUNICHI
IPC: F25D23/02
Filed: 1988-04-19
Abstract: PURPOSE:To eliminate frictional contact with the end of the fin of a gasket and prevent dewing on the outer surface of a door due to the leakage of cold air, by a method wherein a lead wire supplying electric power to a heater in a partitioned body is extracted through a joint provided on the rim of the inner surface of the door so as to penetrate therethrough. CONSTITUTION:A lead wire L is introduced into an outer frame 14A through a hinge 29 and is suspended in the outer frame 14A along the diagonal line thereof while the receiving part of a joint 32 is attached to the end of the lead wire L and the engaging part of a joint case is inserted into both flanges 16A, 17A whereby the lead wire L is fixed. A notch 31 for the inner plate 18A of a door corresponds to the lead-out part 30 of the outer frame 14A and the lead-out part 30 is exposed. The lead wire is not necessitated to be penetrated through the inner plate 18A of the door. The receiving part of the joint 32 is connected to the inserting part 32D whereby the lead wire L at the side of the heater of the partitioning body 25 is connected to the lead wire L on the outer frame 14A. The fin of a gasket is contacted closely with a vertical wall 19A to prevent the leakage of cold air and, therefore, the trouble of generating dew on a frame member 12A may be prevented.
Patent JP-S5619422-A (JP)
Title: Strain detector
Inventor: YAGISAWA TAKESHI
IPC: G01L1/00
Filed: 1979-07-27
Abstract: PURPOSE: To improve the precision of strain detection by sticking a nonmagnetic thin plate to a contact surface between a magnetic sensor and member to be measured and then by measuring variation in magnetic characteristic by use of a difference between outputs of the magnetic sensor and a dummy magnetic sensor.  
     CONSTITUTION: Thin plate 5 made of a wear-resisting nonmagnetic material is stuck to the magnetic-pole end surface of magnetic core 1 coming in contact with structure member 4 to be measured. Setting thin plate 5 large enough in thickness for the work roughness of the surface of structure member 4 nearly eliminates an influence of contact conditions between the surface of structure member 4 and magnetic core 1 upon magnetic characteristics. When the strain of structure member 4 to be measured is detected by use of magnetic sensor 6 like this, magnetic characteristic variation due to the strain is extremely small, so how much magnetic characteristics vary is measured by using a difference between the output of dummy magnetic sensor 6' brought into contact with the surface of a structure material of the same quality free from strain and that of strain detecting magnetic sensor 6. Thus, the precision of strain detection can be improved.

Title: Flow speed sensor driving circuit
Inventor: HIKITA TSUTOMU
IPC: G01F1/68
Filed: 1986-04-23
Abstract: PURPOSE:To measure a flow speed by a single power source, by a method wherein one terminal of a bridge constituted of first and second resistors having the same temp. coefficient is held to constant voltage higher than earth potential and the output of the bridge is differentially amplified to heat the second resistor, and differentially amplified output and constant voltage are differentially amplified. CONSTITUTION:When a power source is turned OFF, resistances are R1=R2 and Rf=RS, and, when said power source is turned ON, voltage Va-Vb is applied to both terminals of a bridge and, because RS is not heated by Rf, a value of voltage V1-V2 is determined by (r). The voltage V1-V2 is differentially amplified by a differential amplifier 9 to heat RS by RH. Therefore, voltage v2 increases and voltage v1-v2 is reduced to become v1-v2 0 at last by a feedback system. The voltage Va of a power source 1 is applied to differential amplifiers 9, 10 and, in order to adjust amplified output V by a volume, voltage Va is converted to Vb<Va by a constant voltage circuit 2 to set voltage Vb to apparent earth potential and inherent earth potential is regarded as a negative power source to be applied to the -VEE terminal of the differential amplifiers 9, 10 and input offset is subjected to zero adjustment to make voltage V equal to voltage Vb. Voltage V0 showing a true flow speed is obtained from the output V0=V-Vb of the second differential amplifier 10.

Abstract: PURPOSE:To make possible the easy detection of potential with a simple device and good accuracy by developing the surface potential formed under predetermined conditions on a latent image carrying body to a sensible image by the developing bias potential predetermined by a developing device and detecting the toner deposition thereof. CONSTITUTION:A bias changeover control circuit 32 changes over the developing bias potential of a bias power source 30 to +950V at the timing when the next uniform electrostatic charge part on a photosensitive drum 2 passes the developing device 4. A density detecting circuit 27 operates at the timing when the uniform electrostatic charge part passes the density detecting position of density detectors 25, 26. The circuit 32 decreases successively the developing bias potential of the power source 30 at the respective timings when the respective uniform electrostatic charge parts on the drum 2 pass the developing part 4 in the same manner thereafter. The circuit 27 operates at the timings when said uniform electrostatic charge parts pass the density detecting positions of the density detectors 25, 26. The sticking of a toner to the uniform electrostatic charge parts on the drum 2 by the device 4 is started from the point of the time when the potential thereof is made approximately the same as the developing bias potential.

Abstract: PURPOSE:To quickly perform processing by allocating a field indicating the processing level in a field indicating the interface register number and starting a detecting logic of address conflict or the like at the time of coincidence between contents of the processing level field and the current processing level of a processor. CONSTITUTION:Contents of the processing level field are comported with the current processing level in the processor; and if they do not coincide with each other, the following instruction is executed in the time overlap processing by a pipeline because execution of the following instruction is not affected. If they coincide with each other, the check logic is started because there is probability of address conflict or the like, and the overlap processing is performed by the pipeline if conflict does not occur. Since the following instruction is inhibited from pipeline processing by actions of these deciding logics only when conflict occurs, unnecessary delay of the start of the following instruction is prevented to quickly perform the processing.
